+README for git hooks script
+===========================
+git has a way to run scripts, which are invoked by specific git commands.
+The git hooks are located in `<mbed TLS root>/.git/hooks`, and as such are not under version control
+for more information, see the [git documentation](https://git-scm.com/docs/githooks).
+
+The mbed TLS git hooks are located in `<mbed TLS root>/git_hooks` directory, and one must create a soft link from `<mbed TLS root>/.git/hooks` to `<mbed TLS root>/git_hooks`, in order to make the hook scripts successfully work.
+
+Example:
+
+Execute the following command to create a link on linux from the mbed TLS `.git\hooks` directory:
+`ln -s ../../git_hooks/pre-push pre-push`
+
+Similarly, on Windows while running as administrator:
+`mklink pre-push ..\..\git_hooks\pre-push`
+

+# Called by "git push" after it has checked the remote status, but before anything has been
+# pushed. If this script exits with a non-zero status nothing will be pushed.
+#
+# This hook is called with the following parameters:
+#
+# $1 -- Name of the remote to which the push is being done
+# $2 -- URL to which the push is being done
+#
+# If pushing without using a named remote those arguments will be equal.
+#
+# Information about the commits which are being pushed is supplied as lines to
+# the standard input in the form:
+#
+# <local ref> <local sha1> <remote ref> <remote sha1>
